Build a great ignition system with a set of Vulcan 8.5mm ignition wires for racing level spark delivery. The spiral-wound copper conductor has low resistance just 25 ohm per ft. The wires are high dielectric strength insulator and heavy glass braid, covered with heavy-duty black silicone jacket and high-temperature gray boots to resist damage from heat and abrasion.

Set includes terminals for engines with early type (socket) and late type (HEI “spark plug top”) distributor caps. Boots and terminals factory are installed on one end. Coil Wire Included.

These Fire Boots are designed for extreme protection of spark plug boots and wires, in excess of 2000°F (1093.3 C) continuous and 3000°F (1648.9 C)
This style is used from ultimate race cars to motor homes.
